Study Notes

PNF Patterns

PNF patterns are used for rehabilitation of musculoskeletal conditions with altered neuromuscular control.
They involve multi-joint, multiplanar, diagonal, and rotational movements for developing strength, endurance, facilitating stability, and mobility.
PNF patterns use sensory cues and diagonal patterns for optimal neuromuscular responses.

PNF Basic Procedures

Manual contacts are often placed over agonist muscles.
Resistance is applied to facilitate movement and inhibit pain.
Therapists should face the direction of the moving limb to apply resistance via body weight.
Visual cues should be provided for enhanced movement control.
The movement pattern should be taught from start to finish.
Coordinated motion and appropriate body positioning are critical.
Timing of the movement is an essential component.

Diagonal Patterns (Upper Extremity)

D1: Shoulder extension, abduction, internal rotation; elbow extension, forearm pronation; wrist and finger extension. Cue: "squeeze my finger, turn your palm up, pull your arm up & across your face," then "open your hand, wrist & fingers up, push your arm down & out."
D2: Shoulder flexion, adduction, internal rotation; elbow extension, forearm pronation, finger flexion. Cue: "open your hand, turn it to your face, lift your arm up & out, point your thumb out". Then "squeeze my finger & pull down across your chest."

Diagonal Patterns (Lower Extremity)

D1: Hip extension, abduction, internal rotation; knee extension, ankle plantarflexion, foot eversion. Cue: "foot & toes up & in, bend your knee, pull your leg over & across".
D2: Hip flexion, abduction, external rotation; knee flexion, ankle dorsiflexion, foot inversion. Cue: "foot & toes up & out, lift your leg up & out".

PNF Strengthening Techniques

Rhythmic stabilization: Alternating contractions of agonist and antagonist muscles in a movement pattern.
Slow reversal: Slow, controlled contractions of a muscle, alternating directions of movement.
Slow reversal hold: Slow reversal with a hold at the end-range of motion.
Alternating isometrics: Alternating isometric contractions of agonists and antagonists.
Alternating rhythmic stabilization: Alternating isometrics with rhythmic stabilization.

PNF Stretching Techniques

Designed mainly for improving flexibility.

Rood's Approach

A neurophysiological and developmental approach used to treat CNS disorders focused on normalizing tone through gradual development of purposeful movement patterns.
Main principles include normalizing tone, respecting gradual development, purposeful movement restoration, and repetition/practice.

Rood's Approach: Techniques

Facilitatory Techniques: Used for improving tone in flaccid muscles by stimulation with tactile cues.
- Distal to proximal application.
Examples: Fast brushing, light touch, tapping, quick stretch, resistance.
Inhibitory Techniques: Used for reducing tone in spastic muscles, Proximal to Distal Application.
- Examples: stroking (slow and firm pressure), neutral warmth, approximating or compressing joints.
